The wafer trapdoor spiders, family Cyrtaucheniidae, are a widespread family of spiders that lack the thorn-like spines on tarsi and metatarsi I and II found in true trapdoor spiders (Ctenizidae).
Deinopidae, also known as net casting spiders, is a family of cribellate spiders first described by Carl Ludwig Koch in 1850. It consists of stick-like elongated spiders that catch prey by stretching a web across their front legs before propelling themselves forward. These unusual webs will stretch two or three times their relaxed size, entangling any prey that touch them. The posterior median eyes have excellent night vision, allowing them to cast nets accurately in low-light conditions. These eyes are larger than the others, and sometimes makes these spiders appear to only have two eyes. Ogre-faced spiders (Deinopis) are the best known genus in this family. The name refers to the perceived physical similarity to the mythological creature of the same name. This genus also includes the humped-back spiders (Menneus).
Ant spiders are members of the family Zodariidae. They are small to medium-sized eight-eyed spiders found in all tropical and subtropical regions of South America, Africa, Madagascar, Australia-New Guinea, New Zealand, Arabia and the Indian subcontinent. Most species are daytime hunters and live together with ants, mimicking their behavior and sometimes even their chemical traits. Although little is known about most zodariids, members of the genus Zodarion apparently feed only on ants; a number of other genera in the family are apparently also ant specialists.
Crevice weaver spiders (Filistatidae) comprise cribellate spiders with features that have been regarded as "primitive" for araneomorph spiders. They are weavers of funnel or tube webs. The family contains 18 genera and more than 120 described species worldwide.
Scaffold web spiders (Nesticidae) is a family of araneomorph spiders closely allied with tangle web spiders. Like the "Theridiidae", these spiders have a comb of serrated bristles on the hind tarsi that are used to pull silk bands from the spinnerets. It contains 16 genera and about 300 species, many of which are associated with caves or overhangs. The genus Nesticus is the type for the family and is found throughout the world. The related Eidmannella has speciated considerably in Texas caves and includes some extremely localized species that are considered threatened. One species, Eidmannella pallida, is found in caves and under overhangs, but also in agricultural fields and other habitats away from such restricted areas. The genus Carpathonesticus is found in central Eurasia.
Velvet spiders are a small group of spiders almost entirely limited to the Old World, with exception of a few species known from Brazil. The characteristics of this family of spiders are that they are entelegyne, eight-eyed araneomorph spiders that build unkempt webs. They are cribellate. Some species are nearly eusocial, lacking only a specialized caste system and a queen. They cooperate in brood rearing, unlike most other spiders except for some African agelenid spiders in the genus Agelena and a few others.
Nemesiidae, also known as funnel-web trapdoor spiders, is a family of mygalomorph spiders first described by Eugène Simon in 1889, and raised to family status in 1985. Before becoming its own family, it was considered part of "Dipluridae".
Austrochilidae is a small spider family with ten species in three genera. Austrochilus and Thaida are endemic to the Andean forest of central and southern Chile and adjacent Argentina, while Hickmania is endemic to Tasmania. The monophyly of the family and the relationships among the genera are uncertain as of May 2017.
Periegops is a genus of spiders with six eyes instead of the usual eight. It is the only genus in its family (Periegopidae) and has three described species. It was long considered to be members of Sicariidae or Segestriidae until Raymond Forster elevated them to the family level in 1995.
Archaeidae, also known as assassin spiders and pelican spiders, is a spider family with about ninety described species in five genera. It contains small spiders, ranging from 2 to 8 millimetres long, that prey exclusively on other spiders. They are unusual in that they have "necks", ranging from long and slender to short and fat. The name "pelican spider" refers to these elongated jaws and necks used to catch their prey. Living species of Archaeidae occur in South Africa, Madagascar and Australia, with the sister family Mecysmaucheniidae occurring in southern South America and New Zealand.
Coneweb spiders (Diguetidae) are six-eyed haplogyne spiders that live in tangled space webs, fashioning a cone-like central retreat where they hide and lay eggs. It is a small family, containing only two genera with fifteen species and is confined to the New World, preferring deserts. Members of the genus Diguetia usually build their webs in shrubs or between cactus pads. They have the same eye arrangement as the venomous recluse spiders, but none are known to be harmful to humans.
Caponiidae is a family of ecribellate haplogyne spiders that are unusual in a number of ways. They differ from other spiders in lacking book lungs and having the posterior median spinnerets anteriorly displaced to form a transverse row with the anterior lateral spinnerets. Most species have only two eyes, which is also unusual among spiders. A few species of Caponiidae variously have four, six or eight eyes. In some species the number of eyes will increase when the spiderling changes its skin as it grows towards adulthood.
Udubidae is a family of araneomorph spiders, most of whose members were formerly placed in the family Zorocratidae, which is no longer accepted.
Hexurella is a genus of spiders, found in the United States and Mexico. It is the only genus in the family Hexurellidae.
Sidymella is a genus of spider in the family Thomisidae, found in South America, Australia and New Zealand. It was originally named Sidyma, but this was later found to have been used already for a genus of moths.
Diplothele is a genus of mygalomorph spider in the family Barychelidae, containing four species restricted to India and Sri Lanka.
Anepsion is a genus of orb-weaver spiders first described by Embrik Strand in 1929.
Davus, also known as the tiger rump tarantulas, is a genus of spiders in the family Theraphosidae (tarantulas). It was formerly included in Cyclosternum.
Michael I. Saaristo was a Finnish arachnologist, with a particular interest in the spiders of the Seychelles. The World Spider Catalog lists 61 genus names or synonyms and 109 species names or synonyms of which he is the sole or co-author.
Jerzy Prószyński is a Polish arachnologist specializing in systematics of jumping spiders. He is a graduate of the University of Warsaw, a long-term employee of the Siedlce University of Natural Sciences and Humanities and the Institute of Zoology of the Polish Academy of Sciences in Warsaw.
